Match List-I with List-II List-I Tetrahedral Complex (A) TiCl4 (B) [FeO4]2- (C) [FeCl4]- (D) [CoCl4]2- List-II Electronic configuration (I) e^2, t2^0 (II) e^4, t2^3 (III) e^0, t2^0 (IV) e^2, t2^3 Choose the correct answer from the option given below:

1. (A)-(I), (B)-(III), (C)-(IV), (D)-(II)
2. (A)-(IV), (B)-(III), (C)-(I), (D)-(II)
3. (A)-(III), (B)-(IV), (C)-(II), (D)-(I)
4. (A)-(III), (B)-(I), (C)-(IV), (D)-(II)

Correct answer: (A)-(III), (B)-(I), (C)-(IV), (D)-(II)

Solution

The correct option matches the tetrahedral complexes with their respective electronic configurations based on the oxidation states and coordination numbers of the metal ions involved. For example, TiCl4 has a d0 configuration, making it e^0, t2^0, while [FeO4]2- corresponds to a specific oxidation state leading to e^2, t2^0.
